SPECIFICATION forming part of Letters Patent No. 242,685, dated June 7,1881.

Application filed March 25, 1881. (No model.)

To all whom it may concern:

Be it known that I, URA H. PALMER, of Green Spring, in the county ofSeneca and State of Ohio, have invented certain new and usefulImprovements in Wheat-Heaters; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings,

. which form part of this specification.

My invention relates to wheat-heaters; and it consists in a heaterconstructed substantially as will hereinafter be described, andspecified in the claim, whereby the grain is thoroughly heated by meansof direct contact with heated air. j

In the drawings, Figure 1 is a vertical sectional view of my heater.Fig. 2 is a detached view of the inclines through which the: grainpasses, showing the mannerof perforating the same.

A is the frame or outer case of my heater, which is preferably made ofmetal. a is a hopper,which is placed on the top of the frame or case A,and serves as a means for feeding the grain to the heater.

BB B B are a series of inclines, made of perforated sheet metal, whichlead from the bottom of the hopper a and extend diagonally across theframe or case A and from side to side of the same.

0 is a discharge pipe or passage, which is placed below the last of theseries of inclines B B B B d is a dust-board, of which there may be onebelow each incline, which serves to collect the dust which may fall fromthe grain as it passes At the lower portion of this dust-board I providean opening, d, through which the dust may be removed. This opening iskept closed while the heater is in operation, to prevent the escape ofthe heated air.

D is a heater, which may be of any desired or suitable kind, thisforming no part of my invention. e is an opening in the top of the frameor case A, through which the air pa sses after it has performed itswork. 7

The operation of my device is as follows: The hoppera being filled withgrain, the grain passes along the inclineB to the opposite side of theframe or case A, when it passes on the incline B, and so on to the lastincline, when it is discharged through the discharge pipe or passage 0.

It will be seen by the drawings that I per:

forate the inclines B B B B at both top and bottom. My reason for thisis to allow the heated air to pass through the grain as it runs down thesaid inclines and thoroughly warm it. The heated air, as it ascends,passes. first through the grain inthe lower incline and then through thegrain in the next higher one, and so on until it passes 0E through theopening 0. As the grain passes over the inclines the dust or dirt fallsthrough the perforations in the same and onto the dust-board d, where itis collected and removed through the opening (1 in the frame or case A.

In the drawings I have shown only four inclines, B B B B butI do notlimit myself to the number of inclines employed,which may be more orless, as the inclines are shorter or longer.

What I claim is In a wheat-heater, the combinationof the inclines B B BB and dust-board d, substantially as and for the purpose shown anddescribed.

In testimony whereof Iliave signed my name to this specification in thepresence of two subscribing witnesses.

URA H. PALMER.
